Part 13

No. 11. _Rosa odoràta álba_, or White-tea, is not so odorous as No. 8, but blooms more profusely, and grows more freely. The beautiful and neat appearance of the buds, when half expanded, is not surpassed; and when full blown, they are a fine delicate white. The bush in that state is showy, much admired, and scarce; we are not positive of its being hardy.

No. 12. _Rosa Bengal_, or Yellow-tea, is a very free flowerer, the shape of the flower is more like No. 8. than any of the others; the petals are large and gracefully set, having a peculiar scent or flavour, and is of a sulphur colour. We cannot say as to its being hardy, but suppose it as much so as No. 8.

No. 13. _Rosa Venella_, or Venella Scented-tea, is undoubtedly a handsome rose, and has many admirers; colour a bloody velvet; flowers large and very double, rising in the centre more than any of the others; blooming freely, and of pleasant flavour; rendering it altogether a desirable rose.

No. 14. _Rosa belle de monza._ The flower of this rose is flatter than any of the other sorts; the petals are regularly laid over each other, making it very compact; it is about four inches in diameter when well grown; the plant is of quick growth, free in flowering, darker in colour than No. 1, equally as hardy, and ought to have a situation in every garden where roses are grown.

No. 15. _Rosa amaránthe_, is a showy brilliant scarlet rose, flower compact, and of a moderate size.

No. 16. *_Rosa Clintónia_, is a good rose, and in a favourable situation will produce abundantly large, round, and compact flowers, differing in shape from any of the others; colour similar to the provins rose.

No. 17. _Rosa semperflòrens plèno_, or sanguinea, is a celebrated rose, the foliage small, and of a reddish appearance. The flower is well shaped, and of a blood colour; wood of a slender growth, requires some protection in winter, or it will die to the surface of the ground; delights in sandy soil. This rose is frequently called anemone-flowered, though in no respects similar to the character of an anemone-flower. The _Otaheite_ rose is of the same colour, but very inferior.

No. 18. *_Rosa purple sanguinea_, is of a purple colour, same in shape as No. 17, but in size larger; is a good flowerer, making a fine variety. We do not know any similar to it.

No. 19. _Rosa grandvàl_, is a magnificent rose; flower full and large, petals closely set, colour dark crimson. The wood and leaves are like the _Hamilton_ rose, but it grows and flowers more freely. It is scarce.

No. 20. _Rosa Indica álba plèno_, or white China, is a rose of free growth, abundant in flower, and pure white, which renders it very desirable; is larger than No. 1, is greatly admired, and rare; requires rich light soil.

No. 21. _Rosa Magnifier_, _magnificent_, or _magnìfica_. It is known under all these names. The general appearance of the plant resembles No. 19, but the flowers in shape and colour are similar to the garden Provins rose, and nearly as large.

No. 22. *_Rosa florabùnda multiplèx_. This rose is very correctly named, although the plant is of a moderate stature. The whole is covered with immense clusters of various coloured flowers, changing from pink to dark crimson; the flowers very double, and greatly admired.

No. 23. *_Rosa flamæa_, has a very striking appearance, is of a flame colour, and distinct from any other of the China roses; blooms freely, and is a little fragrant, which makes it desirable.

No. 24. *_Rosa Hibbèrtia_, is a superb rose of a light red colour; flower of a common size, double and compact, very fragrant, and abundant in bloom. The buds are of a particular shape, being flat at the extremity where others are pointed. It is highly deserving of a situation, and universally admired.

No. 25. *_Rosa Jacksónia_, is deep red, large, and very double, of luxuriant growth; is more spiny and elastic than any of the China roses that have come under our observation. The plant altogether is unique in its character, and flowers profusely.

No. 26. _R. Adamsônia_, is dwarf growing; has flowers of a beautiful purple velvet colour, inclining to black; and is much admired. When well grown, it will bloom freely.

No. 27. *_Rosa Webestèria._[C] None of the China roses approaches this, except _Hortensia_, and it is much inferior. The rose is very double, and particularly well formed; colour similar to No. 8, with a beautiful rich blush in the centre, flowing to the extremity of the petals. It blooms profusely, and grows freely in light rich soil.

[C] Named in honour of D. Webster, Esq. whose productions deserve a place in every library; and this plant a spot in every garden.

No. 28. _Rosa gigántea._ Without exception, this is the handsomest shaped China rose that has come under our observation, the colour dark crimson, with a few shades through it. The centre is full set; petals regular and large, the flower very double, plant strong, growing and free blooming--it is scarce.

No. 29. _Rosa Washington_,[D] is a very good and distinct variety; the foliage is pale green with red nerves; flower full and compact, the extremity of the petals dark red, the bottom white; showing, when the flower is full expanded, a white centre, and is frequently a little striped; grows well, and blooms freely, in light sandy soil.

[D] Originated on the substantial establishment of D. & C. Landreth, and called by them "Scarlet and White."

No. 30. *_Rosa calyxifòlia_. The calyx of this rose has large leaflets attached to it. It blooms very early, and is of a deep crimson colour, with recurved petals, which give it a singular and beautiful appearance. The young shoots and leaves are of a purple hue. It grows and flowers freely, and is quite characteristic, and surpasses any we know for flowering early in the Green-house or Rooms.

No. 31. _Rosa Montezùma_ (Mexican-rose.) This is an esteemed variety, with large double flowers of a red colour, and when the flowers begin to fade they become darker; it is of a strong growing and hardy nature, much admired, and scarce.

No. 32. _Rosa horténsia._ The buds of this rose are very beautiful before expansion, and when fully expanded, are of a fine colour, assimilated to No. 8; flowers large in proportion to the growth of the plant.

* * * * *

These roses are all of a shrubby nature, and the finest flowering varieties that have come under our observation and culture. The China roses generally are not completely double, though going under the name of double flowers, and having the appearance of such. Those that are mentioned above as _double_ and _very double_ are those that are more double than No. 1, which is a rose that is generally known. The whole of them are much admired, and being now of great variety in colour, shade and aspect, constitute a valuable addition to the Flower-garden. A bed of varieties planted therein in good light rich soil, and well dressed by hoeing deep, raking, &c. during the early stage of their growth every season, will form an ornament varied in colour, unrivalled, and as yet not found in our Flower-gardens. Their nature agrees so well with our summer seasons, that it will not surprise us to see, in a few years, selections of them planted in rows or hedges, dividing the compartments in our gardens.

They are all hardy, but of those that are not perfectly so, we have mentioned the required protection. Any of them that have not been proved hardy in your collections, it would be extremely injudicious to leave them exposed the first winter after planting out. Caution is necessary on every unknown point; therefore, we would recommend to give them slight protection, by a covering of straw, mats, boxes, &c. and if they appear to withstand the winter in perfect safety, they will not need again to be covered.

The best season of the year for pruning them is about the first of this month. In doing so it is not advisable to shorten any of the young shoots, except in cutting off the injured parts, that being the wood most productive of bloom; but where there is old stinted wood, it should be cut out as close to the surface of the ground as the other parts of the bush will permit, with any other of the oldest wood that is too crowded. If the plants have been long established, dig in amongst their roots a little well decomposed manure, and stir and hoe them frequently during the summer.

CLIMBING ROSES.

No. 1. _Rosa Champneyàna._ This celebrated rose has a situation in almost every garden in our city, and forms a great ornament, flowering very profusely in immense clusters from May to November. Many of these having more than thirty buds upon them of a light pink colour, it is sometimes called "Pink Cluster." It is of rapid growth, and does well for covering arbours, fences, or any unsightly object. The foliage is of a lucid green, and the wood very strong in growth. This rose is at present one of the most abundant in flower, the easiest of cultivation, (growing in any exposure,) and in every respect is highly deserving of attention.

No. 2. _Rosa blush Noisettià_ is very similar to No. 1. in habit; the flowers are lighter in colour, and a little larger; but the plant does not flower so profusely during the heat of the season. There is a variety of _Noisettia_ in our gardens, known from this by the bud being more rounded, and another under the name of _Charles 10th_, which has fine large flowers of a dark blush colour.

No. 3. _Rosa red Noisettià_, or what we consider more properly _Scarlet cluster_. It is very distinct from any other of the Noisettias in habit. It is an excellent variety, and blooms abundantly; of a scarlet colour; forming a fine contrast with the two last, which are light in colour, and though not generally known is very desirable.

No. 4. _Rosa moschàta_, musk-scented, or white cluster, is an esteemed rose both for profusion of flower and agreeableness in fragrance. It is not of so rapid growth as the three previous, and may be kept as a bush; though it will grow to a considerable height if protected by a wall or close fence, being tacked thereto. Where kept as a bush, in very severe winters, it is the better of a slight covering, and is the latest flowering rose in the garden. The flowers are frequently on the same bush single, semi-double, and double, but mostly semi-double.

No. 5. _Rosa moschàta supérba_, or superb white cluster. This in habit and appearance is the same as No. 4, only the roses are double, and never vary; which makes it a very superior rose. It is highly esteemed and scarce.

No. 6. _Rosa Aralie Noisettià._ This has been called by some _Purple Noisettià_, (which is a very different rose, and not generally known.) In growth it is similar to No. 4, and could be kept in the same manner. The flowers are of a dark pink colour, very prolific, but not so large as No. 2.

These are all what are termed with us ever-blooming roses, being in flower from May until the buds are destroyed by frost. They should be pruned about the first of this month. The young wood is most productive of bloom; where the branches are too crowded, cut out the oldest wood as close to the ground as is practicable, and any of the dead branches. The shoots when tied to the trellis, arbour, wall, or fence, should be about six inches clear. The branches when made fast to their support ought to be in direct lines, which must at all times be strictly observed. It is very unsightly to see shoots trained crooked, or over each other, and, unsightly or unscientifical as it may be, it is too prevalent in every garden.

No. 7. _R. Bourbòn_ is a double rose of brilliant red colour, petals large, stiff, and neatly set; the flower about the size of a common Provins rose, and finely scented; grows freely. The wood is strong, and undoubtedly it is the finest climbing rose that has come under our observation, and is highly admired.

No. 8. R. _Boursault_. This rose is much thought of in Europe. It is of a purple colour (and once called _Purpurea_), has a little fragrance, flower nearly the size of No. 7; wood more slender, and of very rapid growth, and capable of covering a large space. When in flower it is very showy. The old wood is of a purple colour. There is a white variety of it.

No. 9. R. _Lisle_, is of a light pink colour, about the shape and size of No. 8, grows freely, and flowers abundantly. This and No. 8. are the hardiest climbing roses that we know.

No. 10. R. _microphylla_. This rose is unique in every character, resembling No. 21. more than any other. The foliage is very small and neat, and the calyx thick and bristly. The flowers are produced at the extremity of the young shoots in twos or threes, according to the strength of the plant; they are large and double; the exterior petals large and full; those of the interior are very short and thick set; the colour in the centre is dark, shading lighter towards the exterior; the spines are in pairs on each side of the compound leaves. It is perfectly hardy, and greatly esteemed, and not so subject to be attacked by insects as other roses.

No. 11. R. _Franklinia_, or Cluster-tea, generally flowers well in May and June, but during the remainder of the season the heat appears to be too strong for it, the buds dropping off before expansion. The flower bud is larger than that of the Tea-rose; the petals large but loose, colour light blush.

No. 12. R. _Bánksiæ_, or Lady Banks' rose, is a free growing kind, and has a lucid green foliage; flowers small white clusters with pink centre, very double, and sweet scented; in bloom during May. From what we have seen of it, the spring months appear too changeable for perfecting all its bloom, many falling off from the chilliness of the nights. The plant naturally is an evergreen, but in our city is deciduous; grows best in sandy soil, and should be protected by mats during winter.

No. 13. R. _Bánksiæ lùtea pléno_. The habit and foliage of this are the same as No. 12, and whether hardy or not we have not proved. In Europe it is considered more hardy than the preceding variety. The flowers are larger, of a fine gold yellow, very double, and neatly set. It is considered very pretty.

No. 14. R. _multiflòra_, was amongst the first climbing roses that was planted in this city, and was so highly admired, that twenty dollars were given for one plant. It bears its flowers in close clusters on the wood of last year; the colour is a deep blush; petals thickly set, making it a close and compact small rose; blooming in June. It is losing its celebrity, and giving place to _Champnèy_, _Noisèttia_, _Grevìllii_, &c.

No. 15. R. _white multiflòra_. In all respects same as No. 14, except in flower, which is much lighter, but not a pure white.

No. 16. R. _scarlet multiflòra_, is darker in colour than No. 14, but is not properly a scarlet flower.

No. 17. R. _purple multiflòra_. We suspect that there is some confusion in this plant being confounded either with _Scarlet multiflòra_ or with _Grevìllii_. Plants imported as such have proved to be the latter.

No. 18. R. _Grevìllii_, is a very curious rose, flowered the first time with us in June 1830. It is of the variety of No. 14, and of China origin; growth free and luxuriant; leaves large and deeply nerved; flowers in large clusters, almost every eye of the wood of last year producing one cluster, having on it from eight to twenty roses, according to the state of the plant, each rose expanding differently in colour or shade. Many suppose that they expand all of the same colour, and change afterwards. This is not the case. We have seen them white, pink, red, purple, and various other shades when the bloom expanded; and on two clusters we have observed twenty-two distinct shades of colour. In fact, it is a complete nondescript, having roses, single, semi-double, and double, large and small, and every colour between white and purple, forming, in every garden where it is planted, a wonder of the vegetable world. It is very hardy; an eastern aspect will answer it best, preserving the flowers from the direct rays of the sun, which will keep the colours purer. We readily recommend it to every lover of _Flora_.

No. 19. R. _arvénsis scándens multiplèx_, or double Ayrshire. We imported this rose last year, as being a very double blush, sweet-scented variety. It is highly valued, and said to be more rapid in growth than any other variety, and likewise a profuse flowerer. As far as we know it remains to be proved how it will agree with our climate, and have its high characters substantiated; although we have no reason to doubt the authority we received it from.

No. 20. R. _sempervírens plenò_. This is a most handsome double white rose. The strong shoots of last year will produce a large cluster of flowers from almost every eye, and as a profuse flowering double white climbing rose we have seen none to surpass it. It grows freely, the foliage and wood pure green, leaves much nerved.

No. 21. R. _bracteàta plenò_, double Macartney, is a very fine large double white variety, with strongly marked red edged petals; blooming from May to July. It is very scarce, and grows best in sandy soil.

The best time for pruning those roses which only bloom once in the season, and are of a climbing habit, is immediately after flowering, cutting out all the old wood that has produced flowers, thereby invigorating the young wood that is to bear the flowers the ensuing year; and the stronger the wood of this year can be made to grow, the finer and more profuse will be the flowers. The plants of Nos. 12, 14, 18, and the intermediate varieties, have been pruned on a wrong system. In place of giving them a general dressing in spring, they ought to have it immediately after flowering; the old wood cut out, leaving only the young and such as is of a healthy nature. Avoid crowding them together, and tie them all straight and regular. Never top the shoots except where there is a supply of wood wanted. In spring the only dressing requisite is to cut off the injured shoots or branches, making good the tyings that have given way.

Trellises for these roses are generally made too wide; the shoots cannot be neatly kept to them. They ought never to exceed nine inches between each spar or rod.

There are several species and varieties of climbing roses of high standing in character, but not being perfectly known to us in regard to hardiness, &c. we forbear making any remarks upon them, knowing that much exaggeration exists.

CLIMBING PLANTS.

As shade is much required in this country, and plants suitable for covering arbours, &c. eagerly sought for, we will make a few remarks on those which are preferred for their beauty, growth, hardiness, &c.

_Atragène alpìna_, is a free growing deciduous shrub, with large blush-coloured flowers, which continue blooming from May to July; has small pinnated foliage.

_Clématis viticélla pulchélla_, or double purple virgin's bower, is an esteemed climbing plant; of rapid growth, with large flowers in great profusion from June to September. There are several varieties of the above, two of them single, and it is said that there is likewise a double red.

_C. flámmula_, sweet scented virgin's bower, is of very rapid growth. Established plants will grow from twenty to forty feet in one season, producing at the axils of the young shoots large panicles of small white flowers of exquisite fragrance; the leaves are compound pinnate; in bloom from June to November, but in June, July, September, and October, the flowers are in great profusion, perfuming the whole garden. This is one of the best climbing hardy plants that we know, and it ought to have a situation in every garden.

_C. Virgiàna_, is of rapid growth, and well adapted for arbours; flowers small white in axillary panicles, di[oe]cious, leaves ternate, segments cordate, acute, coarsely toothed and lobed, in bloom from June to August. A native, and a little fragrant.

_C. flòrida plenò_, is a fine free flowering plant, though generally considered a shrub, is more herbaceous than shrubby; the flowers are large double white; in growth will not exceed ten feet in one season.

_Glycine frutéscens_, a beautiful native climbing shrub, known in our gardens under that name, but is properly _Wistèria frutéscens_. It has large pendulous branches of blue (leguminose) flowers, blooming from May to August; pinnated leaves with nine ovate downy leaflets; grows freely.

_Glycine chinénsis_, is given to Wistèria, and is the finest climbing shrub of the phaseolious tribe. The flowers are light blue, in long nodding many-flowered racemose spikes, blooming from May to August profusely; leaves pinnated, with eleven ovate lanceolate silky leaflets, and is of a very rapid growth. We are not certain if it will withstand our winters without protection.

_Bignònia crucígera_, is an evergreen which is very desirable in many situations, being likewise of luxuriant growth. It will cover in a few years an area of fifty feet; flowers of an orange scarlet colour, blooming from May to August.

_B. grandiflòra_, now given to _Tecôma_, has large orange coloured flowers, blooming from June to August, and grows very fast. We are not positive that it will stand our winters without protection.

_B. rádicans_, is likewise given to _Tecòma_, and is a native plant. When in flower it is highly ornamental, but it requires great attention to keep it in regular order, being of a strong rough nature; in bloom from June to August.

_Periplàca græca_, is a climber of extraordinary growth. Well established plants grow thirty or forty feet in one season; flowers in clusters from May to July, of a brownish yellow colour, and hairy inside; leaves smooth, ovate, lanceolate, wood slender, twining, and elastic.

_Hedéra Hélix_, Irish Ivy, is a valuable evergreen for covering naked walls, or any other unsightly object. The foliage is of a lively green, leaves from three to five angled. There are several varieties of it, all valuable for growing in confined shady situations where no other plant will thrive.

_Ampelópsis hederàcea._ This plant is commonly employed for covering walls, for which the rapidity of its growth, and the largeness of the leaves, render it extremely appropriate. There are several species of the genus, all resembling the _Vine_ in habit and in flower.

It is called by some _Císsus hederàcea_, which is certainly improper, this belonging to _Tetandria_, and the former to _Pentandria_.

There are several other plants of a climbing habit, both curious and ornamental; but our limits will not admit of a detail.

DECIDUOUS SHRUBS.

Finish planting all deciduous shrubs in the early part of the month. These plants are generally delayed too long, the leaves in many instances are beginning to expand, thereby giving a check to the ascending sap, which we may safely assert causes the death of one third of the plants, when perhaps the operator or some individual more distantly concerned is blamed.

These shrubs, if properly removed and planted at the exact starting of vegetation, pressing the earth close to their roots when planting, (previously taking care that the small fibres have not become dry by exposure,) will not, by these simple attentions, one out of fifty fail. Those that are late planted should have frequent waterings, and if large, firmly supported, that the wind may have no effect in disturbing the young and tender fibrous roots.

OF PLANTING EVERGREEN SHRUBS.
